I’ve heard from several people that for intakes over 3” in diameter a tune is required. Hybrid racing and skunk2 both state is the description hondata is required for their 3.5” intakes for the car to run properly. I believe their may be a basemap for 3.5 inch intake in hondata otherwise your car may run a little lean until it has a proper tune.

Since it happened after a battery change the ecu probably reset its memory and the fuel trims have to readjust
